scribe the manner in which I have carried it out. i f In the accompanying drawings A is the boXor tub `of the engine; B, the cylinders C, thebrake lever pivoted at y D is a metallic lupright or standard se-` cured `to the brake lever or making a part thereof. A Y

` E is a shaft running in boxes upon the top of theengine. t v

h e is a connecting rod one end of which is pivoted to the standard D and the other to the crank gnpon the shaft E. Upon this shaft is securedwthe cog wheel Gr which engages with the wheel H npon the shaft I, to which is also secured the ily wheel K.

` It `is evident from the connections above described that the motion of the shaft E will be nearly uniform, and that as the brake lever approaches its lowest point its momentum will be very slowly retarded, and

that the brake will pass the dead center,

`they irst commence to start again by the continued motion of the crank. I do :not claim` the application of a fly `wheel to a fire engine or to any other 1na chinery,'but what I do claim as my invention `and desire to secure by Letters Patent \1s i The method herein described of easing the `motion of the brake lever by the attachment of a crank in 'the manner set forth.
